This feature was born out of a heated discussion concerning a certain popular link-shortening/framing app that allows people to place their own calls-to-action on top of other sites. We’re not fans of the idea that someone else can place their own elements on top of your content.
We compare this to someone walking into your lawn and sticking a sign up without your permission. Not cool.
So we created the Frame Buster as a feature that will detect when your site is being framed by any framing app and immediately redirect your visitors to the unframed, original version of your site.
This setting is turned on by default, and we highly encouraged you to leave it that way.
